American fashion designer Luka Sabbat has teamed up with the Los Angeles–based luxury men’s undergarment brand Related Garments for a collection to benefit the charitable organization Help Haiti.

Luka’s father, Clark Sabbat, is a first generation American, born in Haiti, and the father-son duo decided to use this 12-piece collection as an ode to their heritage. The collaboration was inspired by a seven-day trip to Haiti, where they met and interacted with local people. The culture and warm nature of Haiti’s residents prompted the collective to seek out Help Haiti as the beneficiary for the project’s revenue.

The collection contains both men’s and women’s undergarment pieces, as well as men’s socks. On the retail site where the collection is available for purchase, the “Sabbat x Related” line is described as “more than marketing, or the casual exchange of design ideas. For Clark, it means nostalgia and the unbreakable bonds of family. For Luka, it means paying homage. For Mike and David, it means extending the brotherhood of their brand beyond bloodlines.”

Mike and David, the brother duo behind Related Garments, have looked to create a line of stylish basics for men, and now women as well. The team sought out a charity that would give opportunities to local Haitians, and allow them to find success, and keep that positive momentum going. They eventually decided to partner with Help Haiti, whose mission is to “create, through merit and needs based scholarships, a community of young professionals and leaders who will promote a more just society in Haiti.”

The collection is available for pre-sale now on Related Garment’s website, and 12 percent of the net proceeds will go to Help Haiti.
